Also fix seteuid/setuid usage on NetBSD.
Changes from 1.2:
1.5: March 19, 2004
Fix logic errors in dealing with multi-message connections (SMTP RSET,
HELO or MAIL FROM resetting SMTP state). Add cb_abort callback.
1.4: March 13, 2004
Some performance improvements, abort rule evaluation immediately when
no further rules can possibly match. Compile without -Werror, as some
ports generate warnings.
1.3: March 8, 2004
Two bugfixes related to RCPT TO: rule evaluation (DSN options and
multiple receipients would match incorrectly), umask(0177) for pipe,
fix for Solaris daemon() implementation. Improved logging (From:, To:
and Subject: headers, when available).
